Title: "Direct Scattering by Penetrable Media"
Abstract:
We are interested in calculating the scattered field generated by an incident wave to a penetrable medium with compact support. To do so, we represent the scattered field by a volume potential and consider the integral formulation of the scattering problem, which gives us the Lippmann-Schwinger equation. The algorithm presented here is highly accurate, works on an adaptive data structure and solves the resulting linear system with a fast direct solver. Some numerical results will be displayed.
